目的:建立七叶灵颗粒的质量标准。方法:采用薄层色谱法对黄芪、柚皮苷进行定性鉴别;采用高效液相色谱法对黄芪甲苷进行含量测定。结果:定性鉴别阴性无干扰,分离度高;黄芪甲苷线性范围为0.166~1.104μg(r=0.999 1),平均回收率为97.27%,RSD为1.3%(n=6)。结论:所建标准可以用于七叶灵颗粒的质量控制。
Objective: To establish Qiyeling granules quality standard. Methods: Astragalus membranaceus and naringin were identified by TLC. The content of Astragaloside IV was determined by HPLC. Results: The qualitative identification was negative without interference and the separation was high. The linear range of astragaloside was 0.166-1.104μg (r = 0.999 1). The average recovery was 97.27% and the RSD was 1.3% (n = 6). Conclusion: The established standard can be used for quality control of Qiyeling granules.
